Black-bellied Plover molting male 9/3/18

Black-bellieds are North America’s largest Plover being roughly the size of a small gull. There was a second plover with this one that spooked and flew off and which had much less black in the face, throat and belly—a female. This one you can still see the outline of the black breeding plumage starting at the bill and extending down the throat and belly, all the way behind the legs. It’s getting mottled now, beginning the molt into winter plumage. In another few weeks this bird will have a soft mottled gray upperside with a white belly, earning it the name it’s known by outside of North America—the Grey Plover. All plumages of Black-bellied Plovers can be told by black axillaries under the wing, that is they all have black armpits which you can see when they take off or land, or are in flight.
